Title: Improvements in gas blast electrical circuit breakers
IPC: H01H33/83
Filed: 1944-10-20
Abstract: 583,346. Gas-blast switches. BRITISH THOMSON-HOUSTON CO., Ltd., COX, H. E., and WILCOX, T. W. Oct. 20, 1944, No. 20349. [Class 38 (v)] In a gas-blast circuitbreaker the moving contacts 3, 4 are constituted by a series of contact blades pivotally mounted on the periphery of a hollow stationary member 6' and urged by springs 11 into engagement with fixed hollow contacts 2, 5, the whole being enclosed in an insulating pressure chamber 8 into which pressuregas is admitted through an orifice 7. The gas, after depressing contacts 3, 4, exhausts to atmosphere through the nozzles 9 on the fixed contacts, and orifices 10. Insulating packing segments 12 are provided between the contacts 2, 5 and member 6' in order to prevent such an escape of gas as would prevent the contacts 3, 4 from being depressed. The gas may flow outwards from the hollow members 6', 2, 5, in which case the outer chamber 8 would be dispensed with and the mounting of the contact blades reversed. The invention is also applicable to single-break circuit-breakers. Specification 583,345 is referred to.

IPC: C07C233/00
Filed: 1964-05-15
Abstract: The invention comprises compounds of formula <FORM:0996110/C2/1> wherein X is -CN or -CONH2 and R1 to R5 are H or C1- 18-hydrocarbon radicals free of aliphatic C-C unsaturation.  Specific compounds are those in which (a) X is -CN or -CONH2 and each R is H, and (b) X is -CN, R1 and R2 are -CH3, R3, R4 and R5 are H. The cyano-compounds are prepared by reacting a 1-cyano-3-alkylidenecyclobutane with HI to give a 1-cyano-3-iodo-3-alkylcyclobutane and reacting the latter with alkali metal hydride; the products may be converted to the corresponding carbamyl-compounds by reacting them at pH above 7 with H2O2.  The compounds of the invention may be converted by pyrolysis to butadienes of formulae. <FORM:0996110/C2/2> and <FORM:0996110/C2/3>

Title: Method for initiating a welding arc
IPC: B23K9/067
Filed: 1951-08-29
Abstract: 695,077. Welding by fusion. SOC. L'AIR LIQUIDE, SOC. ANON. POUR L'ETUDE ET L'EXPLORTATION DES PROCEDES G. CLAUDE. Aug. 29, 1951 [Aug. 31, 1950], No. 20435/51. Class 83 (iv). A process for initiating a welding arc from a distance between an electrode and a workpiece utilizing a high-frequency voltage is characterized in that a luminous or corona discharge is produced around the electrode and when the electrode is brought near to the work - piece said discharge becomes elongated from the electrode towards the workpiece and initiates the welding arc. A non-consumable' electrode 1, e.g. tungsten, is supported in a holder 2 having an electrically insulating nozzle 3 surrounding the electrode to provide an annular space 4 for passage of an inert gas for shielding the arc. The electrode is connected to a transformer 6 and a winding 7 in which the high frequency current produced by a generator (not shown), is induced. The front part of the nozzle 3 is surrounded by a conducting ring 9 connected either to the welding current conductor 10 or to the ground by a conductor 14, a condenser 11 being provided in series in the conductor 14 to prevent welding current from passing through the conductor 14. The high frequency voltage produces around the electrode a luminous or corona discharge which assumes the form 8 when the electrode is far from the workpiece and the elongated form 8<SP>1</SP> when approaching the workpiece. This lengthening gives rise to an intermediate high frequency arc or spark discharge and then, when the gap is small enough, to a welding arc. When the electrode is cold the corona discharge may be struck by contacting the electrode on a piece of metal, e.g. a fountain pen clip or the blade of a screw driver having an insulating handle. The holder 2 is surrounded by an earthed metallic perforated screen 16. Instead of the ring 9 the outside of the nozzle 3 may be metallized such metal covering being earthed through a condenser as when using a ring.

Abstract: 308,937. Golding, H. D., Leicester, r. D., Hirst, H. S., and Imperial Chemical industries, Ltd. July 18, 1928. '' Acetic acid.-Acetaldehyde in the liquid phase is oxidized to acetic acid by means of air or oxygen in the presence of a catalyst consisting of a small quantity of a cobalt compound, for example, cobalt acetate, with or without the addition of other compounds known to act as catalysts for this reaction, notably manganese compounds, for example, manganese acetate. Acetaldehyde in acetic acid solution coutaining 0.005 per cent of cobalt acetate may be treated with air at 30-40‹ C.; or separate streams of acetaldehyde vapour and of air may be passed into acetic acid containing 0.2 per cent of manganese acetate and 0.002 per cent of cobalt acetate, at, a temperature of 40‹ C. The use of higher concentrations of cobalt acetate leads to the production of carbon dioxide, and is not recommended. The use of manganese acetate alone as a catalyst is referred to.

Title: Continuous process for decolourizing liquors
IPC: C13B20/12
Filed: 1971-04-19
Abstract: 1,274,424. Decolourizing sugar liquors. COLONIAL SUGAR REFINING CO. Ltd. April 19, 1971 [Feb.4, 1970], No.20962/71. Heading C6B. A continuous process for the complete or partial decolourization of aqueous sugar liquors, especially the removal of the phenolic colour content from raw washings, raw sugar solutions or melter liquors, consists in passing the liquor downwardly through a floating bed of a conditioned, pulverulent polyamide, e.g. nylon 66 or a poly- N-vinyl polylactam such as poly-N-vinyl polypyrrolidone (PVPP), at such velocity that particles of colour-loaded or relatively spent polyamide, of increased density, become entrained with the downwardly flowing liquor, and subsequently separating the entrained particles from the liquor. As shown, particles of PVPP fed by a line 10 to a vessel 1 fitted with a mixer 2 are conditioned by water from a line 11 which results in swelling and density reduction of the particles. To assist the subsequent colour adsorption process, in which hydrogen bonding is involved, the particles are rendered acidic by the addition of, e.g. hydrochloric acid, to the water. The conditioned or flocculent particles are separated from excess liquid in a filter 3 and returned to the vessel 1 where a sugar liquor such as raw washings is added from a line 12 after which excess liquid is again removed at 3 and the particles are fed by a line 14 to the decolourizing column which is maintained at a suitable temperature by a jacket or heater. The sugar liquor to be decolourized is supplied at 15 and its downward flow rate adjusted so that the particles, which are buoyant in the liquor, remain in the upper part 4a of the column until they become colour-loaded when, due to an increase in density, they are entrained in the outflowing liquor and separated in a filter 5, regenerated at 6 and returned by a line 17 to the column. The regeneration involves successive treatments with water, alkali, water and acid. The flow-rate through the column, of which several may be connected in series, may be adjusted by varying the height of a goose-neck outlet or by means of a pump.
